Uploading Online Ruins Gifs

Hi! When I publish my project (pitch deck) online, most of my gifs will not work at all. They don’t play. I’ve placed a bunch of them in smaller frames for layout purposes and I understand this may cause a problem but the layout has to be what it has to be. I have the most recent version of InDesign, I’ve tried most troubleshooting options, but I’m looking for something to help me. 

To Adobe: it is disgusting that an industry standard software is so grossly incapable of handling this. I’ve worked around the clock for days to get this presentation to my client and I now have to consider upending everything and moving to a different software because the publish online feature is simply not built to handle tough things. I paid so much money for your service and feel disheartened that all my work has gone down the drain.
